While nobody was paying much attention, Amazon created a free, nationwide wireless network that reaches 90% of the US population. It’s called Sidewalk.
It used to be open only to select developers. But Amazon this week made software and hardware development kits available to the public, along with a test kit for checking connectivity.
I first wrote about Sidewalk here in 2019, when the service was announced. Amazon launched it to select partners in 2021.
